Was small electric vehicles, power battery "obsession" range of problems need to be careful to stay

If from the world's first electric car, electric cars now at least 185.During this long exploring process, electric cars, after several twists and turns, but each time the twists and turns and power battery has almost all the links.Today, when is given priority to with the electric car of new energy vehicles cause global attention, while China is to be raised to the national development strategy level, hope the spring breeze to realize auto field corner overtaking, realizing the dream car power.But without exception, the core of the power battery technology, security, recycling and capacity are plagued by trying to power is in the car.Not only the traditional car companies, now has been at the forefront of small electric vehicles is faced with many power battery.

High demand and high risk concerns range

Some experts pointed out that if the structure of the simplified car, the car is mainly composed of most quantity, namely energy device and power equipment.The former power raw material and the latter is responsible for the conversion of mechanical energy.From this perspective, simplify the structure of the electric car, it mainly contains two elements, namely the battery and motor, thus the role of power battery is obvious.

As early as 1912 electric cars, once into the glorious period, at this moment, in the electric car total more than the world hundreds of thousands of units.But this brilliant only retained for more than 20 years, with the dramatic increase in world oil production, oil has been found relatively more battery can realize the value of the power device.With the fuel tank and engine for mileage is no longer a people fear.And the popularity of gas station more convenient than charging equipment popularization.

History always has a remarkable enlightenment function of reality.Whether high speed car, car at low speed, charging and the problem of life always is a big confusion when consumer choice.But is this, have more advantages to solve the problem of small electric vehicles.
As is known to all, small electric vehicle's mission is to solve the problem of short walking of the people's livelihood.The requirement for range is relatively low.In pursuit of lightweighting design, battery burden much smaller for small electric vehicles.But this year the frequent accidents in the field of new energy vehicles or exposes many problems of power battery, security is at that time the focus of public opinion.

Comprehensive public reporting is not hard to find, the current of the electric car battery technology in the high-speed development of our country at the same time also highlighted problem.First, power battery lack of technology, foreign markets dependent on a number of core technology, such as the temperature of the battery problem, structure, etc.;Second, is the lack of evaluation system, although now part of the electric vehicle running in our country is very good, but the lack of a good evaluation system.How about the safety of the battery, for example, under the environment of high temperature and low temperature can work normally, in these areas is still lack of complete evaluation system.

Experts pointed out that the moment beyond the battery level to do the electric car is a kind of aggressive behavior, lead to the electric car PaWo also unavoidable, even cause serious burning accident, it brings to the state, enterprises and individuals will be waste and the dangers of life and property.For electric vehicle development, therefore, be sure to distinguish the status quo and sort functions.High speed car should focus on high speed car research and development, the low speed car to focus on solving the basis of travel demand.On the range and speed of concrete analysis to specific issue.For small electric vehicles, to safety in the appropriate range perfectly, for small electric vehicles "this feet" production "fit" shoes.

Experts point out that the reasonable pure electric vehicle mileage is 150 km, if improve the mileage, curb weight will increase, the increase in the number of the battery pack will be under the existing power battery technology, if forced to improve life will expose apparent irrationality.Known as tesla, 85 KWH battery pack, according to the Chinese academy of engineering academician Yang, tesla has so far burned cars, and the perpetrator is battery.In order to change this situation, it is said that tesla doing separate energy affordable car, and not simply to do high-end cars.

So our country should be the amount of battery power and set standards, development of low speed minivans, don't go for high-speed car, battery cannot burden models.

After range Small electric vehicles need to be treated with caution

Returned to the small electric vehicles, if the business motivation to build national car, it must be firmly fastened before "national car" "safe" two characters.Just don't one-sided pursuit of high specific energy.In other words, if a small electric car range should constantly improve, also unceasingly to enhance power battery than energy, the problem is that when the car is still at the time of battery energy security concerns, low-speed car field take what to guarantee, life and safety.

As is known to all, battery is a device that can contain different levels of risk, so some experts suggest, willing to sacrifice some specific energy, also want to use high security priority of the battery.In size of the design of the battery, therefore, to control does not occur in a chain reaction, when a battery has a problem, other batteries to avoid also continue to occur around burning explosion phenomena, the construction safety operation procedures, not to deliberately pursue range battery abuse.

Locate the small electric vehicles is already clear, as a kind of walking vehicle upgrade, it meet the demand of mass is not for the purpose of further, but in a more convenient for the purpose.For example, a vegetable market to buy food, ferry their children to school, work, etc.But the industry now appear a mistake is confusing the vehicle at low speed and the function of high speed car, in low-speed car gives too much for high expectations, and try to use the low speed car prices enjoy the travel of high-speed car positioning of "beyond".A penny a points goods, from security considerations, it is not appropriate.

Small electric car has its own mission, meet the daily short-distance travel, so in the pursuit of lightweight design should play its own advantages, and cannot be Mired in the pursuit of high range.Let children wear shoes of adult, run only fall very serious.
